Yikes, it's like spyrograph or something... nice... I need to experiment more with all this trig stuff you guys are pulling.

The standard 'pinwheel':

Code:

1 SCREEN 12
2 FOR colour = 0 TO 15
3 PALETTE colour, colour * 4
4 NEXT
5 angle! = angle! + .1
6 colour = colour + 1
7 IF colour > 15 THEN colour = 0 ELSE IF angle! > 360 THEN angle! = angle! - 360
8 PSET (INT(SIN(angle!) * angle!) + 320, INT(COS(angle!) * angle!) + 240), colour
9 IF INKEY$ = "" THEN GOTO 5

EDIT: There it is with the palette switched.

The non-standard pinwheel:

Code:

1 SCREEN 12
2 FOR colour = 0 TO 15
3 PALETTE colour, colour * 4 * 65536 + (colour * 2)
4 NEXT
5 angle! = angle! + .1
6 colour = colour + 1
7 IF colour > 15 THEN colour = 0 ELSE IF angle! > 360 THEN angle! = angle! - 360
8 PSET (INT(SIN(angle!) * angle! + angle!), INT(COS(angle!) * angle!) + 300), colour
9 IF INKEY$ = "" THEN GOTO 5

edit: just moved it from being centred at 240 to 300 (feels more balanced that way)

This should not be posted here as it's 11 lines but.... Out of contest, off course.

Wizardlife: Your non-standard pinwheel is the best effect i have seen so far! Great!

Lines inside a circle...

Code:

SCREEN 13
DO
WAIT &H3DA, 8
FOR A% = 0 TO 359
PSET (160 + COS(A% * 3.1415 / 180) * 40, 100 + SIN(A% * 3.1415 / 180) * 40), RND
NEXT
A% = INT(RND * 360)
LINE (160 + COS(A% * 3.1415 / 180) * 39, 100 + SIN(A% * 3.1415 / 180) * 39)-(160 + COS((A% + 180) * 3.1415 / 180) * 39, 100 + SIN((A% + 180) * 3.1415 / 180) * 39), INT(RND * 16) + 15
LOOP

well, after that non-standard pinwheel i give up

that 'seizure vision which is not seizure visions on slow computers' is pretty much a bunch of calculated crap thrown together

Here is mine:

Code:

'vortex (Kinda of..) Antoni Gual 2003
1 SCREEN 13
2 OUT &H3C7, 0
3 a$ = a$ + CHR$(INP(&H3C9))
4 CIRCLE (160, 290 - LEN(a$) ^ .79), LEN(a$) / 2.8, LEN(a$) \ 3, , , .5
5 CIRCLE (160, 290 - LEN(a$) ^ .79 + 1), LEN(a$) / 2.8, LEN(a$) \ 3, , , .5
6 IF LEN(a$) < 256 * 3 THEN 3 ELSE OUT &H3C8, 0
7 j = (j + 1) MOD (LEN(a$) - 3)
8 OUT &H3C9, ASC(MID$(a$, j + 1, 1))
9 IF LEN(INKEY$) = 0 THEN 7

thx. I was trying to dig up all the stuff I made my graphing calculator do in grade 10 when we were supposed to be translating parabolas...

I don't think anyone's going to hit rel's plasma for sheer 'cool' factor, tho.

I really like that falling text one. *runs away to watch the matrix dvd*
